•
First number should be number of points in the following harness data. If this
number and actual number of points do not match then tester gives error.
•
Data is to be entered net by net, each net separated by a carriage return and line
feed i.e. press “ENTER” after every net only. End the data with“#” on the last line.
•
Each point is separated by a space i.e. type space between each points.
•
Any other character will not be recognised by tester.
Label Data, date / time, barcode, harness name etc. :
•
Files should have extension “FILENAME.LBL”.
•
Label Data can be an edited file or a pure ASCII file generated by a label
printing software. Preferably file size should be less than 200 bytes for each harness.
4.4: Testing and Test Results
4.4.1: Testing:
Press “TEST” key and wait till display “PUT CABLE” after that mount the harness to be
tested on the rig. The display will be “PASS nnnn” with audible beep sound for good
harness along with the count or directly errors (details in following section) will be
displayed for faulty harness. For a faulty harness; the tester will stop at first occurred fault
and test the same harness repeatedly and keep on displaying the same fault. It proceeds
only when the fault is removed. The tester will pass the harness only if it finds correct
harness as per selected test mode, “circuit by circuit” or “all circuits”.
When a harness is passed; in auto mode of testing, tester displays “REMOVE
CABLE”; meaning remove cable / harness from the rig. Tester will keep on checking if
the harness is removed completely. When harness is removed completely, the display will
be “PUT CABLE” i.e. indicating that there is no harness on the board and operator should
mount harness. Now the harness is to be mounted. Once tester finds a circuit mounted on
rig, it starts testing the harness and displaying first occurred fault. Hence test key is
required to be pressed only once to start the test. Now only the next harness is to be
mounted.
To leave test mode Analyse‘A’ key can be pressed.
If a harness name is entered
for that cable number, tester will display name in place of “cable”.
When a harness is passed in manual mode, tester keeps displaying “PASS” and
next test starts only after pressing test key.
